In partnership with Apple iTunes U, Illinois Vision 20/20 has launched this new initiative. The 21st Century Learning Center is an open and accessible collection of education resources. It will initially focus on grades 9-12, with expansion for grades K-8 currently in the initial development stages. Resources include lectures, videos, books, and other materials available for high school courses such as Algebra I and II, chemistry, geometry, ELA 9-10, ELA 11-12, economics, biology, and physics. More course options will be added this fall.
